Okay, so here's what I do upon creating a .pack file -- either MOVIE or MOD format as I've tried both to no avail.
I open the editor. I select "Use Vanilla TSV" and then begin editing unit values. The values I edit are: Melee Attack, Melee Defense, Morale and Charge; while making Bronze Shield Pikemen have rome_pike_elite for primary melee weapon, gave Spartan Heroes a 1.2 experience modifier and I gave shield wall to Triarii.
After editing the stats until I'm satisfied, only modifying some 6 units mind you, I hit save one more time and then I click on "Get TSV." Then, I open PFM 3.03, click open and select the .pack file that you supplied in the Pack folder.
After renaming the TSV files to match the DB entries (by removing "mynew_" without the quotes) I click on Import TSV for each entry.
I don't modify anything else after doing so. Then I click on Save As, then name the file, and save it to my directory (inside the Data folder where the mods go.) When I load up the game, I check for changes in Custom Battle. This is what's striking me as odd, and I can't seem to fix it. Every unit EXCEPT for the ones that I modified now has Hastati Bireme unit cards. The units that I did edit keep their normal unit card. However, NO units retain the changes the I made to their stats.
What exactly am I doing wrong? The TSV files that I got after editing in the Editor are: building_units_allowed; cdir_military_generator_unit_qualities; land_units; land_units_to_unit_abilites_junctions; main_units; unit_experience_threshold_modifier; unit_set_to_unit_junctions; unit_variants; units_to_groupings_military_permissions.
EDIT: Okay, so, I managed to get the unit cards back to normal by deleting entries that weren't necessary. However, the unit stats are still not changing. They are just staying at their default values.
Forgot to mention earlier but I'm not using the Beta Patch 3; I'm on Patch 2. Not beta patch 2, normal patch 2.
